EE230: Signals & Systems

EE230, Signals and Systems, introduces the Fourier and Laplace transforms as methods to model and analyze continuous-time linear systems (primarily first and second-order circuits) in the frequency domain. Parallels between the time and frequency domains are discussed, and sampling and filter design issues are developed. The course makes extensive use of Matlab as a computational and visualization tool. Labs reinforce theory and develop hardware skills. Prerequisites: EE 223 and MA311. (3 lecture hours)


Lecture Schedule

In the following table, the readings and homework are assigned on the day listed and due on the following lesson. The readings are taken from the custom-printed class textbook unless otherwise noted. Some problem sets are downloaded below and completed by the student on engineering graph paper. Others are links to online electronically-graded problems that are due 10 minutes prior to the start of class - make sure you have saved your work by then. You already registered with Connect system in the fall EE223 semester here which grants you access to the online text and problems.  If you bought the EE223 text through the bookstore, the last page of the text gives code to register with Connect good for 2 semesters; if you purchased the text elsewhere you must buy Connect access directly through the link to complete the E-Assignments.
